Magnetic Scattering | NNSS 2025 at ORNL

Magnetic Scattering Presented by Pat Clancy 1st National Neutron Scattering School, 2025 Oak Ridge National Laboratory (ORNL) In this lecture, Pat Clancy provides an overview of magnetic neutron scattering and explains why neutrons are uniquely powerful probes of magnetic materials. The presentation is designed to introduce the fundamental principles behind magnetic scattering and to illustrate the types of scientific questions that can be addressed using neutron techniques. Clancy discusses how neutrons interact with magnetic moments in solids, enabling direct measurement of magnetic structures and excitations. The lecture outlines how magnetic neutron scattering experiments reveal information about spin arrangements, magnetic order, and dynamic phenomena in quantum and correlated materials. Emphasis is placed on understanding what experimental observables represent physically and how scattering data can be used to answer questions about magnetic interactions and collective behavior. Drawing on experience from reactor and spallation neutron facilities, including work with spectrometers such as ARCS and disk chopper instruments, the lecture situates magnetic scattering within the broader landscape of neutron instrumentation. The goal is to provide students with both conceptual grounding and practical insight into how magnetic neutron experiments are designed and interpreted.
